naked earth - topography - bathymetry Low-poly 3D model

earth topology / bathymetry model based on NASA Earth Observations datasets.

although this is meant to be scientifically accurate, note that the height is exaggerated by a factor of about 100 -- the distance between the tallest/lowest points is about 10% of the radius. On the real Earth, this ratio is close to 1/10 of 1% depending on how its defined.

the ratio of the 'depth of the deepest point in the ocean' to the 'height of the tallest mountain' is 80 / 64.

the models are based on icospheres build of equilateral triangles, with displacements applied from the NASA datasets. This means that the model is relatively homogeneous -- there is no quality loss around the poles.

includes

• 5M poly uncompressed model [eg icosphere with displacements based on data]

• 1M poly uncompressed model [eg icosphere with displacements based on data]

• 1M poly model based on quadratic decimation of 5M poly model

• 100K poly model based on decimation from 5M poly model

• original NASA data PNGs

does not include UVs but can take trivial spherical texture mapping
